  • Thumbnail Image for Distilling Head, Short Path

    Designed for use with small quantities where hold up between the flask and receiver must be kept to a minimum. The thermometer bulb and stem serve as column packing. Upper hose connections are for cooling lines while the lower connection is for vacuum. Available with Vigreux indentations to improve...

  • Thumbnail Image for Distilling Receiver, Moisture Test, Barrett

    Barrett style distilling receiver used to determine the water content in petroleum or bituminous material. Receiver is made according to ASTM specifications, with the addition of the top outer standard taper joint and lower stopcock. Available with glass or PTFE stopcocks.

  • Thumbnail Image for Distilling Adapter, Angled

    Adapter is designed for use with flasks or reaction vessel lids that have a 10 or 20° angled side neck. Adapter has a lower inner joint and two top outer joints. Lower stopcock is either a 6mm or a 10mm PTFE stopcock with a 1/2” or 3/4” OD distillate takeoff for use with a...

  • Thumbnail Image for Adapters, PTFE, Thermocouple

    PTFE adapter for use with either 1/8"; or 1/4"; thermocouples. Adapter has an outer Viton® o-ring to form a grease-free, airtight seal between the adapter and the listed size of outer joint. The compression nut works in conjunction with the upper Viton® to provide a airtight seal...

  • Thumbnail Image for Adapters, Inert Gas, Inner Joint

    Adapter has two hose connections 180° from one another to permit a flow of inert gas over the apparatus. Hose connection has an O.D. of 10mm at the largest serration.

  • Thumbnail Image for Distilling Receiver, Moisture Test, Barrett

    Similar to CG-1261 but with the uptake tube vacuum jacketed to improve distillation performance. The jacket eliminates the possibility of condensation or recrystallization of distillate in the sidearm.

  • Thumbnail Image for Adapters, Inlet, Inner Joint, 90°

    Allows for flexible tubing to be connected to apparatus for introduction of vacuum or pressure. Hose connection has an O.D. of 10mm at the largest serration and is bent downward at a 90º angle to the inner joint.

  • Thumbnail Image for Adapters, Flow Control, Glass Stopcock, 90°

    Used to regulate the flow of gases or liquids into reaction systems. Stopcock has a bore of 2mm and is supplied complete with a CG-423 retaining clip. Hose connection has an O.D. of 8mm at the middle serration.

  • Thumbnail Image for Adapters, Inlet, Inner Joint, 90°

    Allows introduction of reactants below the interior surface. Hose connection has a O.D. of 10mm at the largest serration and is bent downward at a 90º angle to the inner joint.

  • Thumbnail Image for Adapters, Flow Control, PTFE Stopcock

    Used to regulate the flow of gases or liquids into reaction systems. PTFE stopcock has a bore of 2mm. Hose connection has an O.D. of 8mm at the middle serration.

  • Thumbnail Image for Distilling Adapter

    Chemglass

    Compact and simple distilling adapter for use with Chemglass process reactors. Vapor flows upward freely and distillate is collected in to the small bowl below the joint and through the stopcock into a distilling receiver. Adapter has a lower inner joint and is available with one or two top outer...

  • Thumbnail Image for Adapters, Vacuum Take-Off, Vertical

    With standard taper top outer and lower inner joints with sealed in drip tip. Serrated hose connection has an O.D. of 10mm at the largest serration for connection to vacuum source.

  • Thumbnail Image for Adapters, Distillation, 105°

    Distillation adapter with sealed in lower drip tip and top outer joints, both being the same size.

  • Thumbnail Image for Adapters, Moisture Test

    Adapter used to construct a simple moisture trap. Add a condenser to the top outer joint and a graduated funnel to the lower inner joint. Adapters with larger center to center spacing can be used with process reactors and larger flasks up to 50L.

  • Thumbnail Image for Adapters, Distillation, Claisen

    Distilling adapter having an outer member on the vertical side tube for use with a thermometer of the listed joint size and immersion. Sidearm has a standard taper inner drip tip joint while vertical tube has a top outer and lower inner joint, all being the same size. FOR THERMOMETERS SEE CG-3506-N.

  • Thumbnail Image for Adapters, Inlet, Inner Joint, 90°

    Allows PTFE tubing to be connected to apparatus for introduction of vacuum or pressure. 1/2" OD ground swagelock is designed for use with a standard 1/2" TFE, PFA, or polypropylene compression fitting.
